This work presents the results of a study whose aim was to determine the
influence of algal blooms on precipitation of heavy metals. The scope of
the study covered culture of a mixed population made up of Scenedesmus
and Pseudokirchneriella algae in experimental conditions and initiating
a metal biosorption process with the use of culture biomass by
administering ions of Zn(II) and Ni(II). The process was controlled by
assessing the level of biosorption of metals entered at a one-off basis
in the form of Zn(II) and Ni(II) salts or in the form of mixture of both
ions, in comparison to the control sample, at different exposure times
(2 hours and 24 hours). The presence of metals was determined both in
the biomass and in the culture medium. The presented results of the
study confirm the effectiveness of Chlorophyta in the process of zinc
and nickel biosorption. A phenomenon of competitiveness between the
metals was observed when they were administered at the same time.
